| <div class="block">Lightweight, reusable class for specifying ranges of byte[]'s. |
| <p> |
| <code>ByteRange</code> maintains an underlying byte[] and a viewport into that byte[] as a range of |
| bytes. The <code>ByteRange</code> is a mutable, reusable object, so the underlying byte[] can be |
| modified after instantiation. This is done using the <a href="#set(byte%5B%5D)"><code>set(byte[])</code></a> and <a href="#unset()"><code>unset()</code></a> |
| methods. Direct access to the byte[] is also available via <a href="#getBytes()"><code>getBytes()</code></a>. The viewport is |
| defined by an <code>offset</code> into the byte[] and a <code>length</code>. The range of bytes is |
| 0-indexed, and is accessed by index via the <a href="#get(int)"><code>get(int)</code></a> and <a href="#put(int,byte)"><code>put(int, byte)</code></a> |
| methods. |
| </p> |
| <p> |
| This interface differs from ByteBuffer: |
| </p> |
| <ul> |
| <li>On-heap bytes only</li> |
| <li>Raw <code>byte</code> access only; does not encode other primitives.</li> |
| <li>Implements <code>equals(Object)</code>, <code>#hashCode()</code>, and <code>#compareTo(ByteRange)</code> so |
| that it can be used in standard java Collections. Comparison operations are lexicographic, which |
| is native to HBase.</li> |
| <li>Allows the addition of simple core methods like the deep and shallow copy methods.</li> |
| <li>Can be reused in tight loops like a major compaction which can save significant amounts of |
| garbage. (Without reuse, we throw off garbage like |
| <a href="http://www.youtube.com/watch?v=lkmBH-MjZF4">this thing</a>.)</li> |
| </ul> |
| <p> |
| Mutable, and always evaluates <code>#equals(Object)</code>, <code>#hashCode()</code>, and |
| <code>#compareTo(ByteRange)</code> based on the current contents. |
| </p> |
| <p> |
| Can contain convenience methods for comparing, printing, cloning, spawning new arrays, copying to |
| other arrays, etc. Please place non-core methods into <a href="ByteRangeUtils.html" title="class in org.apache.hadoop.hbase.util"><code>ByteRangeUtils</code></a>. |
